pattern-algebra@0.1.0

Minor Changes

• d2ee2df: Initial release of the pattern-algebra package.

  This package re-exports all functionality from @pattern-algebra/core, providing a simpler import path for users who prefer an unscoped package name.

  // Instead of:
  import { parsePattern, matchPath } from '@pattern-algebra/core'
  
  // You can use:
  import { parsePattern, matchPath } from 'pattern-algebra'

  Both packages provide identical functionality - choose whichever import style you prefer.

Minor Changes

• 7cd829e: ## New Features

  Pattern Algebra Operations

  • Added patternIntersect(), patternUnion(), patternComplement(), and patternDifference() for set operations on compiled patterns
  • Patterns can now be combined using standard set algebra

  Automaton Improvements

  • Added DFA size limits to prevent exponential state blowup during determinization
  • determinize() now accepts DeterminizeOptions with configurable maxStates (default: 10,000)
  • Added AutomatonLimitError for handling state limit exceeded conditions
  • Added SegmentMatcher interface for composite pattern matching without faking RegExp

  Path Utilities

  • Added PathContext interface for path resolution operations
  • Updated normalizePath() to properly handle ~, relative paths, and project roots

  Bug Fixes

  • Fixed createIntersectionPattern to use proper SegmentMatcher instead of fake RegExp object with invalid properties

  Documentation

  • Added comprehensive JSDoc documentation to all interface properties in type definitions
  • Documented PathContext usage in README
  • Added examples for pattern algebra operations

  Tests

  • Added 38 new tests for automaton operations:
    • 14 tests for determinize() including state limit handling
    • 15 tests for isEmpty(), findWitness(), and countPaths()
    • 9 tests for complement() operation
